I don't get post-exertional malaise now at all. I regularly do high-intensity spin cycling ("Soul-cycle" style, which activates the adrenals very significantly) and don't get malaise. I've also done plenty of weights training and jogging (up to 10km/6mi), over the past year, and again, post-exertional malaise is just never an issue. Up until about 3 years ago, a solid weight training session (squat/bench/deadlift) would have me overstimulated and unable to sleep that night, then crashing for 7-10 days.
